Ultrafiltration membrane has a wide range of applications and good industry development prospects

Ultrafiltration membrane is a polymer semipermeable membrane, usually made of polymer materials, such as cellulose acetate ester, polysulfone, polyethylene, polyamide, etc. After years of development, there is currently an adequate supply of domestic polymer materials, and representative production companies include Guochu Technology, Daqing Huake, etc., which is conducive to the development of the ultrafiltration membrane industry.

According to different materials, ultrafiltration membranes can be divided into organic membranes and inorganic membranes. Inorganic membranes mainly include ceramic membranes and metal membranes, while organic membranes can be divided into polysulfones, fluorine materials, polyolefins, and polyvinyl chloride according to different materials. and other larger types, among which ultrafiltration membrane products made of polypropylene, polyacrylonitrile, polyvinylidene fluoride, polytetrafluoroethylene and other materials are the most widely used. According to the structure of ultrafiltration membrane, it can be divided into tubular ultrafiltration membrane, plate and frame ultrafiltration membrane, hollow fiber ultrafiltration membrane, spiral wound ultrafiltration membrane, etc. Each has its own advantages and disadvantages, among which the latter two are more It is suitable for handling large amounts of liquids and has higher requirements in industrial applications.

Ultrafiltration membrane is a pressure-active membrane that can remove colloids, particles and other substances with high relative molecular mass in water. Ultrafiltration membrane technology can remove particles, macromolecules, and proteins such as solutions, and has low operating pressure, large water production, and is easy to operate. It has been used in industrial production, environmental protection, medicine and health and other fields. It is very important for ultrafiltration membranes. Application requirements are higher. According to the “Global and China Ultrafiltration Membrane Industry In-Depth Research Report 2021” released by the Industrial Research Center, with the support of policies, my country’s water treatment industry is developing rapidly, and the demand for ultrafiltration membrane applications continues to rise. It is expected that the size of my country’s ultrafiltration membrane market will reach 22 billion yuan by 2021.

The technical threshold for ultrafiltration membranes is relatively high and subject to technical limitations. Currently, high-end products are mainly concentrated in developed countries and regions such as the United States and Europe. Globally, the United States and China are the main ultrafiltration membrane producing countries, but in terms of consumption, demand in developed countries is higher. Currently, Europe is the world’s largest ultrafiltration membrane consumer region, accounting for about 30% of the market, followed by North America, which accounts for about 21%.

Current global ultrafiltration membrane manufacturers include Koch, Asahi Kasei Industries, Suez Environmental Group, Evoqua, DuPont, Toray, 3M, Mitsubishi and other companies. Benefiting from policy support for the development of the water treatment industry, my country’s ultrafiltration membrane market has attracted many companies to deploy. Currently, the more representative companies include Zhejiang Chuangchuang and Hainan Lisheng.

Industry analysts said that ultrafiltration membranes have more advantages than reverse osmosis membranes and have a wide range of applications, driven by the development of terminal industries. , the domestic ultrafiltration membrane market demand continues to rise, and the industry has developed rapidly. Globally, the ultrafiltration membrane market demand is mainly concentrated in developed countries. my country’s ultrafiltration membrane application market has not yet been fully developed, and the future market development potential is great. In terms of production, there are currently many domestic companies in the field of ultrafiltration membranes, but a leading position has not yet emerged, and there are still development opportunities in the future market.
